TONZ whom t may cancer-n Beit known that I', SAMUEL Masini, a citizeii of the United States, residing at Detroit,

in the county of Vilayne and State ol Michigan, have inventedv a new and useful VImprovement in Indicators,.ot which the following is a specification. i l Y My invention relates to ii'iiprovements in indicators, and refers more particularly to indicators to be attached to a. wall of a vestruction and combination ol' parts hereinafter more fully described with the aid of the accompanying drawings and claimed.,k

In the drawings: y

VFigure l illustrates a-,froiitview of the indicator partly in elevation and partly in section. y f

VFigure 2 is av section o-n the line 2-2 of Figure 1.

Figure 3 is Aa section onthe Figure 1. Y l

Figure 4 shows a detail, and

Figure 5 is a section Von the Figure 4.

Referring more particularly to the drawings, 1 designates a casing provided inthe front with a substantially centrally located opening 34, and, if desired, side openings line 3 3 Of line 5-5 of or other suitable words.

1n the ,casing runways 2 are mounted as Yby braces 3 and 4. The runways are profided with outwardlyy extending `flangesv o end also acts as a contact member as will be mentioned hereinafter.

The llanges ol the runways .2 and the sides ot the lugs 12 limit ill@ .lateral movement the rollers ist.

Above the opening 3st on the casingI usually Write the words The next street is" O n both sides of the casing lateral Vpro- ]ec'tions 15 are provided, in each olwliich there is a magnet 16l c1116 andl a plate' 17' or 17a. The latter vare mounted on levers 18 and '18l respectively which are pivotally at ached lto the ycasing at 19 and 19a, and springs 2O and 20a extend from the outer' ends 21 and 21?? of the lever tothe casing iii such al manner as to tend to draw their plates 17 and 17 e away'lrom the magnets. Stops 37 and 37% which are secured to the lateral projections, limit thedistance of the plates 17 and 17 u from the magnets 16 and 16a. At the opposite ends 22 and 22a ot the. levers feed'fingers' aiidQSa are pivotally arranged and have'arms Ql and 24d. so connected by springs and 25 to the levers 18 andL 18a that the back of the arms-2st andl 2d will normally restagainst the stops Q6 and 26a integral with the levers. Sprockets 27 that VSeach will contactfwith the members 13 on its side of the casing, and are adapted'to be actuated by the leed liiigers and 23a.

Relerring now to the electrical circuits, Y

the source of energy 28 is connected on one sideV by. leads 29 and 30 to themagnets 16y and 16L respectively, and on the other side to one terminal 31 of a, two-way switch. A second terminal 82 of the latter is connected tol the'ma'gnet 16,` anda third terminal 33 of the two-way switch is wired to the.

magnet 16a.

'Vhen' Contact is madelbetween the te r miiials 31 and 32 theinagnet 16 is energized andthe lever 1S is drawn downwards' so .that the feed linger 23 strikes one ot the teeth of `the sprocket 27 and causesthe. latter to turn. The opposite tooth olf the vsprocket then strikes 'one of the members 13 on that side oli' the indicator and forces it upwards causing the endless carrier 6 to move 'upwards until the plate iininediatelybelow side of the casing is turned by the adjacent members 13 it rotates just clear of the feed linger 23a.. -When connection between the contacts 81 and 32 is broken, the spring Q0 'causes the lever 18 to reassume its normal and 27l are also rotatably mounted ,in the lateral projections 15, and are so positioned Htl position. In moving back the upper side of the feed finger 23 strikes the next tooth of the sprocket to the one on which it has just exerted downward pressure and swings downwards about its pivotal point 40 on the lever 18 until just before :the latter reaches its maximum height above the inagnet 16 by which time the feed finger is sut-k ticiently tar above the tooth oi' the sprocket to be released therefrom. As soon as that occurs the spring 25 pulls the feed iinger -back vto its normal position against the stop 26 and it is in position for its next stroke.

The spring 25 must be weak enough t0 al-` low the reed linger to swing vdownwards without turning the sprocket in the reverse direction on its return stroke.

Siinilarl b connectin T the contacts 3l vmembers on each side, rollers mounted on said members, said rollers being adapted to move along said runways, a lateral projectioii on each side of said casing, a sprocket mounted in each projection, said sprockets being adapted to engage said members and move the carrier round the runway, and means for turning the sprockets.

2. In an indicator, the combination as de scribed in claim l, wherein one of the sprockets isadapted to move the carrier in one direction, and the other sprocket is adapteilI to move the carrier in the opposite direction.

3. In an indicator, the combination as described in claim l, wherein a leve'ractuated by a magnet is mounted in each lateral projection and is adapted Vto strike atootli of the sprocket within that projection and cause it to turn, and wherein spring means are provided for returning the levers to normal position. y

In an indicator, thecombination of a casing having an opening therein, endless runways mounted in said casing, a plurality of plates pivotally connected to one another transversely oltheir length, a nameplate receiving groove on each of said plates, a projecting member on eac-h end of said plates, a roller mounted on each oi'said projecting members and adapted to vmove along the runways, a lateral projection on each side otthecasing, a sprocket wheel rotatably mounted in each lateral projection, each sprocket being adapted to contact the projecting members on one side ot the plates and to cause said plates to move round said runway, and means for rotating said sprockets. f

5. In an indicator', the combination as described in claim d wherein a Vmagnet is provided in each projection, a lever having a plate thereon in each projection, spring means for tending to hold said levers and plates in spaced relation fr oinsaid magnets, pivotal iingers on said levers, and spring means for tending to hold said feed fingers in operating position.
